废润滑油再生技术的研究进展

Research Progress for Regeneration Technology of Waste Lubricating Oil

综述了国内外的废润滑油再生工艺的研究现状,探讨了各种工艺技术的优缺点和应用前景。无机膜具有化学稳定性好、温度适用范围广、耐污染能力强、机械强度高、分离效率高等特点,可以在高温下使用,并可以通过清刷或焙烧再生,而且在操作过程中不需要添加任何物质,不会产生二次污染,是废润滑油再生比较好的一种工艺技术。

The research of waste oil regeneration process from home and abroad was reviewed, and the advantages, disadvantages and application prospects of a variety of technology were investigated. Inorganic membrane has the characteristics of good chemical stability, wide temperature ranges, strong resistance to pollution, high mechanical strength, high separation efficiency, can be used in high temperature, and regenerate by clear brush or roasting. There is no need to add anything in the operating process, with no secondary pollution created, so it＇s a better technology for regeneration of used lubricating oil.
